SYCAMORE – A 28-year-old Crystal Lake man accused of being involved in a conspiracy to cook methamphetamine across DeKalb last year was sentenced to 2 1/2 years probation Wednesday.

Corey Lindquist, of the 600 block of Eletson Drive, pleaded guilty Wednesday to possession of methamphetamine precursor in exchange for prosecutors dropping all other counts against him. Lindquist had been facing two methamphetamine-related charges, both of which were punishable by probation or between three to seven years in prison.

Prosecutors said Lindquist was one of 16 participants in a methamphetamine ring centered at Travel Inn in DeKalb. Some who were charged were accused of buying pseudoephedrine, a key ingredient for methamphetamine, court records show.

The operation’s suspected ringleader, Thomas Wilkinson, 29, of DeKalb, was sentenced Feb. 25 to seven years in prison after he admitted to participation in methamphetamine manufacturing.

As part of probation terms, Lindquist cannot consume alcohol and must have a substance abuse evaluation by May 1.
